          Love It!

          I just purchased my 2nd 48V Kong. This is an excellent product and I'm tying my 2 Kong batteries together for my off grid home. The product works well and I will suggest this to anyone who wants energy independence.

          Perfect!

          Shopsolarkits set me up with a customized WHK3. We doubled the panels, doubled the inverters and doubled the batteries! The only parts I’m waiting on is stuff I didn’t purchase thru SSK! Love the fast response time to questions after the sale.

          Big battery are awesome

          I went from the lead acid batteries to the big battery. Totally the best move I have made. We are completely off grid system we got 4 of these batteries and can't wait to get the system completed. There price was a little higher than other batteries we were looking at, but these are US made. Well worth the extra money in my opinion.
